"The show upped its game as far as its own production design — which it's already incredible at," Pascal, tells The Hollywood Reporter. "To be at the center of it, as a character piece in the middle of this world, it was amazing."

Pascal adds "there were extensive fight rehearsals" with Bjornsson to get the scene right.

Others involved in the episode also tease that it will be massive. Director Alex Graves told THR back in March that what comes in Sunday's episode (as well as in the June 15 finale) makes the Purple Wedding seem almost small in comparison.
